I am considering new OEM upper and lower control arm assemblies on my V2, the assemblies come with pre-installed factory bushings, feeling lazy and don't have time right now to remove and replace bushings. Asking for feedback comparison to CS or other after market type bushings. Difference in ride, longevity, etc... I plan to keep the car, so it's not an issue to replace them at some point in the future. Just wanted to know if there might be some compelling reasons to install after market bushings. Thanks...

I’m in the exact same predicament as you. I’m in need of front upper control arm bushings and I believe I will go with new AC Delco control arms.
After reading a few post about the deference between aftermarket or ome, the only thing that I really see is if you are looking to maybe upgrade your suspension for track or course driving then the aftermarket way will be the way to go but if you like the way the car rides as stock then just stay with stock or bushings that are equal to stock bushings.
Good luck either way you decide to go.

Totally agree with hardtimes. If you like OEM ride stay away from aftermarket. Even the “soft” CS provide for a very different ride feel, the “race” bushings are harsh. I’m on the red CS as mine is a total track car, ride is obnoxious with lowering springs and other mods. My Buddy has the black CS bushings on his street ride and they are substantially firmer than OEM. IF, you favor a more “German” ride then you will be fine with the black CS bushings.
As to the install, probably took me 3 to 4 hours to do the front. No special tools required. The biggest issue was pressing in the new bushings. I did have to take that to a friend with a shop and a good press to get that done. If you have a reasonable level of mechanical aptitude it is certainly not that difficult a job. Obviously need a new alignment once all is said and done.
Have fun

I installed bushings and would not do it again. Pretty much everyone with stock UCA bushings with the age of these vehicles can presume they are shot. I ended up pulling out the bushings and arms in the end and replaced them. Keep in mind the car that lapped the Nurburgring in < 8 mins was equipped with OEM bushings so I am not sure how much you really gain by replacing them with urethane besides a harsher ride and potential future squeeks.

I did CS Black and love it. Front end is tighter with a hair more NVH.

After extensive research, I used Prothane Super Grease 19-1751 when I installed them and so far, no squeaks and its been 6 months. I've hit it with the lube gun a month ago while I was doing an oil change... just in case.

I've been running CS reds for the last year and it's definitely more aggressive than stock but nothing overly dramatic.

+1 on the reds. Nice and firm but not overly harsh.
